What to change
Ask your supplier to keep the final attachment list aligned with the visitor's latest removal or replacement choice, even when an earlier transfer finishes late.
A worked example
Illustrative example
A visitor removes an accidentally chosen leaflet while it uploads, then selects the intended document. Only the replacement remains attached after both operations settle.
Why this matters to your practice
Removing an attachment should be a reliable instruction. A late upload response must not quietly put the removed file back into the request. Ask your supplier to demonstrate cancellation while a harmless test file is still transferring, then immediately choose a replacement. Wait until both operations have settled before reviewing the final attachment list. The visible list and the files included in the test submission should agree, so the visitor remains in control of what they send.
A practical review example
A visitor accidentally selects one leaflet, removes it while it uploads and immediately chooses another. Ask your supplier to reproduce that timing with harmless files. Wait until both operations settle, then compare the visible list with the attachments in the final test submission. The first file should not quietly return or overwrite the replacement's progress. Removing its row from the screen is only part of the result; the cancelled operation must also stop changing what the website says will be sent.
How to check the result
Accept when cancellation remains effective and later transfer events cannot reverse the visitor's current selection.
A mistake to avoid
Hiding the file row immediately is a visual change, not proof that the unfinished operation can no longer affect the submitted attachment set.
